Carlos,

You need to ensure that your widget "Búsqueda DM" is preloaded in your config.xml

preload = "true"

SERESCO__S_A_SERESCO__S_A_

Hello,

I put it as example.

My code was :

        function timerComplete( event:TimerEvent ):void
        {
         timer.removeEventListener(TimerEvent.TIMER_COMPLETE, timerComplete);
         var id:Number = SiteContainer.getInstance().getWidgetId("Búsqueda DM");
         
         var bWidget:IBaseWidget = SiteContainer.getInstance().widgetManager.getWidget(id) as IBaseWidget;
          
         if (bWidget){
          var bWidg:BaseWidget = bWidget.getInstance();
          var vSW:BuscarDerechoMinero = bWidg as BuscarDerechoMinero;
          vSW.buscarDerecho(id_Derecho);
         } else {
          var bWidget2:IBaseWidget;
          bWidget2 = SiteContainer.getInstance().widgetManager.getWidget(id) as IBaseWidget;
          var vSW2:BuscarDerechoMinero = bWidget2 as BuscarDerechoMinero;
          vSW2.buscarDerecho(id_Derecho);
         }
        }

and the config.xml

<widget label="Búsqueda DM" icon="com/esri/solutions/flexviewer/assets/images/icons/i_derecho.png" menu="menuWidgets" config="com/esri/solutions/flexviewer/xml/BuscarDerechoMinero.xml">com/esri/solutions/flexviewer/widgets/BuscarDerechoMinero.swf</widget>

this lines always returns null

var bWidget:IBaseWidget = SiteContainer.getInstance().widgetManager.getWidget(id) as IBaseWidget;
...         
bWidget2 = SiteContainer.getInstance().widgetManager.getWidget(id) as IBaseWidget;

and in this function, moduleTable and widgetTable always has 0 elements.

 public function getWidget(id:Number):IBaseWidget
      {
       var widget:IBaseWidget;
       var label:String = configData.configWidgets[id].label;
       var icon:String = configData.configWidgets[id].icon;
       var config:String = configData.configWidgets[id].config;
       var url:String = configData.configWidgets[id].url;
       var preload:String = configData.configWidgets[id].preload;
       
       if (widgetTable.containsKey(id))
       {
        widget = widgetTable.find(id) as IBaseWidget;
        widget.setState("maximized");
        var wObj:DisplayObject = widget as DisplayObject;
        scrollToWidget(wObj);
       }
       else
       {
        //module loaded
        if (moduleTable.containsKey(url))
        {
         var modInfo:IModuleInfo = moduleTable.find(url) as IModuleInfo;
         widget = modInfo.factory.create() as IBaseWidget;
         widget.setId(id);
         widget.setTitle(label);
         widget.setIcon(icon);
         widget.setConfig(config);
         widget.setConfigData(configData);
         widget.setMap(map);
         var widgetDO:DisplayObject = widget as DisplayObject;
      widgetBox.addChild(widgetDO);
         widgetTable.add(id, widget);
        }
        else
        {
         return null;
         loadWidget(id, url,preload);
        }
       }
       return widget;
      }

Help me!! jeje.

Thanks in advance

Linoxmg,

Are you sure that

var id:Number = SiteContainer.getInstance().getWidgetId("My Widget Label");

is the name of your search widget as it is defined in your config.xml?...

SERESCO__S_A_SERESCO__S_A_

Hello,

First at all, sorry for my English.

Robert I need help on your code...

I modified all the files:
BaseWidget.as
IBaseWidget.as
SiteContainer.mxml
MapManager.mxml
WidgetManagerDocked.mxml
...

But I allways obtain the same error... (null reference) in the MapManager.mxml

function timerComplete( event:TimerEvent ):void
        {
         timer.removeEventListener(TimerEvent.TIMER_COMPLETE, timerComplete);
         var id:Number = SiteContainer.getInstance().getWidgetId("My Widget Label");
         var bWidget:IBaseWidget = SiteContainer.getInstance().widgetManager.getWidget(id) as IBaseWidget;
          
         if (bWidget){
          var bWidg:BaseWidget = bWidget.getInstance();
          var vSW:myWidget= bWidg as myWidget;
          vSW.myQueryFunction(id);
         } else {
          var bWidget2:IBaseWidget;
          bWidget2 = SiteContainer.getInstance().widgetManager.getWidget(id) as IBaseWidget;
          var vSW2:BuscarDerechoMinero = bWidget2 as BuscarDerechoMinero;
          vSW2.buscarDerecho(id_Derecho);
         }
        }

bWidget and bWidget2 are "null", and debugging into the code,...WidgetManagerDocked.mxml and function getWidget() the widgetTable and moduleTable vars are always lenght 0.

The widget ID is correct.

Can you help me?

Thanks in advance

Naty,

I am not sure what you have the function in your SearchWidget called...

Try adding this function to your SearchWidget.mxml if you don't have it.
//Add to your SearchWiget.mxml

   //query parameter
   public function querybmpid(sParam:String):void
   {
    
    var i:Number = cboLayerText.selectedIndex;
    queryLayer = configSearchText.url;
    if(queryExpr){
    }else{
     queryExpr = configSearchText.expr;
    }
    queryFields = configSearchText.fields;
    queryTitleField = configSearchText.titlefield;
    queryLinkField = configSearchText.linkfield;
   
    if (queryLayer)
    {
     var queryTask:QueryTask = new QueryTask(queryLayer);
     var query:Query = new Query();
     var pExpr:String = sParam.toUpperCase();
     var expr:String = queryExpr.replace("[value]", pExpr);
     query.where = expr;
     query.outFields = queryFields.split(",");
     query.returnGeometry = true;
     query.outSpatialReference = map.spatialReference;
     queryTask.execute(query, new AsyncResponder(onResult, onFault));  
     showMessage(loadingLabel, true); 
     showStateResults(null);   
                
             // on result
     function onResult(featureSet:FeatureSet, token:Object = null):void                
     {   
      try
      {
       var recAC:ArrayCollection = createRecordData(featureSet);
       addSharedData(widgetTitle, recAC);
       wRepeater.dataProvider = recAC;
       showMessage(selectionLabel + " " + featureSet.features.length, false); 
       onLoadDone(null);
       map.cursorManager.removeAllCursors();
      }
      catch (error:Error)
      {
       showMessage(error.message, false);
       onLoadDone(null);
      }
       
       }
      
     //on fault
     function onFault(info:Object, token:Object = null) : void
     {      
      onLoadDone(null);              
      showMessage(info.toString(), false);         
     }
    }  
   }
If you call it querybmpid like above it should match the MapManger.mxml of Sandra's that I told you to switch to.

This is definitely not an easy piece of code to implement as there are many vital steps to the code that need to be in place and it helps if you try to understand the path that the code is taking.

Basically the application loads and check is there is a URL Parameter for the search and if there is once the map is loaded then programatically launch the SearchWidget and pass that parameter to it and run the query. So the MapManager needs to check for the paramter, find the search widget and launch it and then when you have the reference to the searchwidget call the (what ever function i.e. queryPPIN) and execute the search. So the MapManager has to call a valid function in the SearchWidget.

Naty,

So you are missing more code that was discussed in the original tread then.
//In BaseWidget.as add

        private static var _Widget:BaseWidget;

//Then in the initWidgetTemplate function add

   _Widget = this;
The QueryPID error means that you need to look in your SearchWidget for a public function called QueryPID. In the original thread I called it "public function queryPPIN(sParam:String):void".

The CustomDraw error means that your MapManager code is now looking for my EnhancedDraw widget instead of the standard draw tool of ESRI's. That code was not in Sandra's MapManger code so If you are not using my custom draw widget than I would say look back up at the beginning of this thread and grab Sandra's MapManager code she posted.

Thank u so much Robert, I m newbie with flex..
now I just cant find the original thread I called it "public function queryPPIN(sParam:String):void 😞

Sandra,

Try this

public function querybmpid(sParam:String):void
   {
    
    var i:Number = cboLayerText.selectedIndex;
    queryLayer = "http://arcgis.sd.gov/Arcgis/rest/services/BMP2/MapServer/0";
    queryExpr = "BMPID = '[value]'";
    queryFields = "*";
    queryTitleField = "BMPID";
    queryLinkField = "";

SandraPanicucci

This is the line from my config.XML --- "BMP Locations" is the layer name in the map which contains the BMPID attribute.

<mapservice label="BMP" type="dynamic" visible="true" alpha="1" icon="com/esri/solutions/flexviewer/assets/images/icons/i_flag.png">http://arcgis.sd.gov/ArcGIS/rest/services/BMP2/MapServer</mapservice>>

I tried changing this to simply "BMP" which is what it sounded like you were saying it should be...the map service id/Label... got rid of the mapmanager.mxml error that popped up on the site but still leaves me with
***Error #1009: Cannot access a property or method of a null object reference***
on the SearchWidget

I guess that means I'm one step closer. I believe my problem now lies in this ---

public function querybmpid(sParam:String):void
   {

    var i:Number = cboLayerText.selectedIndex;
    queryLayer = "http://arcgis.sd.gov/Arcgis/rest/services/BMP2/MapServer/0";
    queryExpr = "BMPID = '[value]'";
    queryFields = "BMPID";
    queryTitleField = "BMPID";

Section of the SearchWidget but many changes later I guess I still need help.

RobertScheitlin__GISP

Sandra,

Ok this line is the culprit

refreshLayer("BMP Locations",30000);

so is "BMP Locations the exact map service id/Label that you have in your config.xml?

SandraPanicucci

Looking much better! Thank you... It is going to the Search Widget but now I get the following errors.
***this in an error box on the site***

Here is your code fixed.

Just replace the MapLoadComplete function in your MapManger.mxml with this one.

//map load complete
   private function mapLoadComplete(event:MapEvent):void
   {
    SiteContainer.dispatchEvent(new AppEvent(AppEvent.LAYER_LOADED, false, false, null));
    try
    {
     if (ExternalInterface.available)
     {
      var result:URLVariables = new URLVariables();
      var urlSubstring:String = ExternalInterface.call("window.location.search.substring", 1);    
      if (urlSubstring && urlSubstring.length > 0)
      {
       result.decode(urlSubstring);
       // Parse URL
       var xParam:String;
       var xExt:String;
       if (result["BMPID"])
        xParam = result.BMPID;
       if (result["EXT"])
        xExt = result.EXT;
       
       if (!xParam = ""){
        var timer:Timer = new Timer(4000, 1);
        timer.addEventListener(TimerEvent.TIMER_COMPLETE, timerComplete);
        timer.start();
       }
       if (!xExt == ""){
              var extArray:Array = xExt.split(",");
        var extent:Extent = new Extent(Number(extArray[0]), Number(extArray[1]), Number(extArray[2]), Number(extArray[3]),map.spatialReference);
        map.extent = extent;
             }
       
       function timerComplete( event:TimerEvent ):void
       {
        timer.removeEventListener(TimerEvent.TIMER_COMPLETE, timerComplete);
        var id:Number = SiteContainer.getInstance().getWidgetId("Search");
        var bWidget:IBaseWidget = SiteContainer.getInstance().widgetManager.getWidget(id) as IBaseWidget;
        
        if (bWidget){
         var bWidg:BaseWidget = bWidget.getInstance();
         var vSW:SearchWidget = bWidg as SearchWidget;
         vSW.querybmpid(xParam);
        } else {
         var bWidget2:IBaseWidget;
         bWidget2 = SiteContainer.getInstance().widgetManager.getWidget(id) as IBaseWidget;
         var vSW2:SearchWidget = bWidget2 as SearchWidget;
         vSW2.querybmpid(xParam);
        }
       }
      }
     }
    }
    catch (error:Error){}
    refreshLayer("BMP Locations",30000);
    //uncomment if you are using my enhanced draw widget
    //map.addLayer(drawgLayer);

Eventually I want the 10572 to be a number fed in from a different website but for now I'll be happy to get it to work with just that one. Unless what I hope to be able to do doesn't sound like it will work with the direction I'm heading here.

Sandra,

I guess I will need you MapManger.mxml also. Line 587 in your SearchWidget.mxml that the error references is telling me that the querybmpid function is not receiving the query parameter (10572)

SandraPanicucci

URL of the website = http://arcgis.sd.gov/server/denr/bmpviewer/index.html?BMPID=10572
BMPID being the attribute I wish to search on. Hope you can make sense of this mess. Thanks for looking.

Can you attach your SearchWidget.mxml and the URL that you are using for this?
